A 3-TO-2 WIRE CONVERSION CIRCUIT FOR A TMR, SOLID STATE, MAGNETIC SENSOR

May 1, 2021
Two-wire interfaces are found commonly in proximity sensing functions. (e.g., any application with a door, lid, or cover, a proximity sensing function indicates to the system whether the door, lid, or cover is open or closed). In many legacy designs the proximity sensing function is implemented with a reed switch and magnet or an electromechanical…
